Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] This paper proposes a new method to realize that voice exchange can be performed locally - local exchange. The so-called local switching is to establish a channel for exchanging local user plane data between two base stations when both the calling party and the called party are in the same base station or different base stations linked by the IP network (between two base stations) establish a service channel for voice transmission), after the channel is established, there is no user plane data (uplink and downlink) transmission between the base station and the BSC, and the uplink and downlin...

Abstract

In order to simplify the transmission flow of voice data in a communication system, the invention provides a local switching communication method. The method comprises the following steps that: a first base station and a second base station respectively perform the signaling interaction with corresponding base station controllers (BSC) to build a corresponding first communication channel, wherein the BSC acquires communication information of the first base station and communication information of the second base station during the signaling interaction; the BSC corresponding to the first base station sends the communication information of the second base station to the first base station; the BSC corresponding to the second base station sends the communication information of the first base station to the second base station; and according to the communication information of the first base station and the communication information of the second base station, a second communication channel is established between the first base station and the second base station through an internet protocol (IP) network and the first communication channel is released. In addition, the invention also provides a local switching communication system.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a local exchange communication method and system. Background technique [0002] As the GSM mobile communication network becomes more and more mature and the existing technology becomes more and more stable, the voice switching part during the call is habitually considered to be carried out in MSC (Mobile Switching Center) or BSC (Base Station Controller), and then With the use of IP (Internet Protocol) network as the connection link between the base station and BSC is becoming more and more common, and the use of satellite environment as the connection network between the base station and BSC, the transmission link between the base station and BSC is becoming more and more more complicated. For the transmission of voice data, it has brought many adverse effects, such as time delay, jitter and packet loss. [0003] legacy voice exchange [0004] During a call,...
